PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 668,807, dated February26, 1901'.

Application filed December 31, 1897. Serial No. 665.031. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, WILLIAM SPALCKHAVER,

a citizen of the United States, residingat Brooklyn, county of Kings,and State'of New York, have invented certain new and useful Improvementsin Printing-Machines, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

This invention relates to printing machines, and has been designedespecially with a view of providing a machine for taking proofimpressions.

The invention aims especially to provide an t5 improved constructionwhereby thelength of the web advanced for each impression and thelengtliof the printed sheet are made to correspond with the length of the form.

As a full understanding of the invention zo can best be given by adetailed description of a preferred construction embodying all thefeatures of the invention, allpreliminary description will be omitted,and such a detailed description will now be given in connection z5 withthe accompanying drawings, showing such a preferred construction, andthe features forming the invention will afterward be speciiicallypointed out in the claims.

In said drawings, Figure l is a side view of 3o a bed-and-cylinderprintingmachine conf structed to embody the invention. Fig. 2 is an endview looking in the direction of the arrow 2 in Fig. l and parts beingshown in section on line 2 of Fig. 1. Fig. 3 is an enlarged longitudinalsectional View of the impression cylinder and coacting parts and partlytaken on line 3 of Fig. 4. Fig. 4 is a detail plan view showing theform-lock and associated parts. Fig. 5 is a View, partly 4odiagrammatic, of the im pression-cylinder and `coacting parts taken justinside the frame looking in the direction of the arrow in Fig. 2. Fig. 6is a side View of some of the parts shown in Fig. 5, but in a differentposition. Fig. 7 is a plan view ofthe parts shown in Fig. 6. Fig. 8 is adetail section on the line 8 of Fig'. 4. Fig. 9 is adiagrammatic View ofthe impression-cylinder,the web-feeding devices,

thereon in positionjust before the beginning 5o of an impression. y

Referring to t-he drawings, the various op'- erating parts of themachine are su pported in a suitable frame A. The form bed B is mountedto reciprocate horizontally on supportingrolls 10, being guided bygroo\es 11 in the side frames, as shown in Fig. 2. The bed isreciprocated by means ofr two endless sprocket-chains 12 13,-turning atone end of their run on sprocket-wheels 14, mounted 6o on studsextending inwardly from the side frames, and at the other end on drivingsprocket-wheels 15, carried by short shafts 16, each of which shafts 16carriesa pinion 17, meshing with a gear 18 on the driving-shaft 65 20,Connected to a link of each of the sprocket-chains 12 13 is adriving-pin 21, which carries a box 22, mounted to ride in a verticalgroove or guideway 23, formed in a hanger 24, carried by the bed. Bythis con- 7o struction as the sprocket-chains are driven by the drivingsprocket-wheels 15 they will through the pin 21 and box 22 move the bedin one direction or the other, according as the links carrying the pin21 are travelingin the 75 upper or lower path of the sprocket-chains. Asthe links carrying the driving-pin arrive at the driving sprocket-wheelsafter having moved through the upper path of the chains to the left inFig. 1, as indicated by the ar- 8o row,and move downward around thesprocketwheels the driving-pin and box 22, moving with said links, slowdown, and then stop the movement of the bed to the left in Fig. 1 as thebox moves downward in the slot 23 of the 85 hanger 24, and then startand accelerate its movement to the right, and then as the pincarryinglinks leave the sprocket-wheels 15 the bed will be moved at a uniformspeed to the right until the pin-carrying links reach 9o thesprocket-wheels 14, when the movement of the bed will be graduallydecreased, stopped, and then started and increased in the oppositedirection as the pin-carrying links turn upward about thesprocket-wheels 14, carrying the box 22 upward in the slot 23. Then thebed will be again moved at a uniand the front portion of the bed, with aform 1 form speed to the left.

The impression-cylinder C is journaled in journalboxes 25, mounted toreciprocate vertically in standards 26, extending upward from the frameA at either side of the machine, which journal-boxes 25 are lowered tohold the cylinder C in printing position when the bed is being moved tothe left in Fig. l and raised to elevate the impression-cylinder duringthe return movement of the bed. The journal-boxes 25 are thus raised andlowered by means of cams 27, carried by the camshaft 28, one at eitherside of the machine, through pitmen 29, pivoted one to each journal-boxand having forked ends embracing the ends of the shaft 28 and carryingrolls running in the cams 27. The cam-shaft 28 carries a gear 30,meshing with a pinion 31 on the driving-shaft 20, these gears being ofproper relative size to cause the cam-shaft 28 to make one revolution t0each complete reciprocation of the form-bed B, and the cam 27 beingformed to give the desired movements to the journal-boxes 25. Theimpression cylinder C is driven so as to rotate at a surface speedcorresponding to the movement of the bed during its printing movement bymeans of a rack 32, carried by the bed, and a gear 33, carried by thecylinder.

The roll of paper WV is supported by the upper ends of the standards 26,an adjustable tension-band 34 being preferably provided to bear on atension-disk 35 on one end of the shaft carrying the web-roll. The webis led from the web-roll past a guide-bar 40, between feeding-rolls 41and 42, over a guide 43, and between cutting-blades 44 and 45 to theunder side of the impression-cylinder C to be entered between thecylinder C and the form carried by the bed B for printing. Thefeeding-roll 41 is driven by frictional contact with a driving-roll 46,mounted in arms carried by the journal-boxes 25, said roll beingprovided with a gear 47, meshing with the gear 33, carried by theimpression-cylinder. 'lhe feeding-roll 42 is preferably mounted so as tobe adjustable toward and from the feeding-roll 41, as by being carriedby eccentrics 48, arranged to be operated through handles 49,and securedby set-screws, as shown clearly in Fig. 1. The feeding-101141 ispreferably a rubber-covered roll, as indicated in Fig. 3.

The feeding-rolls 41 and 42 and the cuttingblade 45 are carried by aframe 50, pivoted on a shaft 51, so that by rocking the frame 50 thefeeding-roll 4l may be moved into and out of position to contact withthe driving-roll 46, and the cutting-blade 45 maybe moved into and outof position to eoact with the stationary blade 44. The pivot-shaft 51 ispositioned between the feedingroll and the blade 45 so that when theframe is rocked so as to bring the feeding-roll 4l in contact with thedriving-roll 46 the cutting-blade 45 will be moved away from the blade44 to allow the paper to pass freely between them and when the frame isrocked to carry the feeding-roll 41 away from the driving-roll. The

blade 45 will be thrown forward to coact with the blade 44in severingthe web. This rocking frame is under tension, as by a coiled spring 52,which tends to rock it, so as to hold the feeding-roll 41 in contactwith the drivingroll 46; but it is normally held in its nonfeedingposition-that is, with the feedingroll 41 out of contact with thedriving-roll 46-by means of a pivoted latch 55, having a right-angularslot 56, which engages a pin 57, carried by a downward extension of 011eside of the frame 50. As the bed is advanced to carry the form beneaththe impression-cylinder for printing, before the front end of the formreaches the cylinder an abutment formed by a stud or roll 60, carried bythe bed, engages the under side of an inclined cam-plate 6l on the latch55 and throws the lat-ch upward from the position shown in Fig. 6 tobring the horizontal portion of the rightangular slot 56 opposite thepin 57 on the rocking frame 50, thus releasing the frame, which is thenrocked by the spring 52 to carry the feeding-roll 41 into contact withthe driving-roll 46, as shown in Figs. 1 and 5, thus causing thefeeding-rolls to advance the web downward over the guide 43. Theposition of the abutment 60 longitudinally of the bed is such as tocause the feeding of the web to begin in time so that the forward end ofthe web will be advanced from the cutting-knives in time to enterbeneath the impression-cylinder in advance of the front end ot' theform. As the printing movement of the bed continues,the rocking frameremains in the position shown in Fig. 5 until a cam 62, carried by thebed, engages a stud or roll G3, carried by a link 64, pivoted to theframe 50, and guided by a pin 65, extending from the frame A through aslot in the link. The cam 62 draws the link G4 downward, thereby rockingthe frame 50 against the tension of the spring 52 from the positionshown in Fig. 5 to that shown in Fig. 3, whereby the cutting-blade 45 isthrown to coact with the blade 45 to sever a sheet length from the web,and the feeding-roll 41 is carried away from the driving-roll 46 to stopthe feed of the web, the pin 57 being also brought beneath the verticalportion of the right-angular slot 56 in the latch 55, thus allowing t-helatch to fall and lock the frame in this position. The frame 50 thenremains in its nonfeeding position until the web is again to be fed asthe bed begins its next printing movement.

In order that thc latch 55 shall not be raised to release the frame onthe return movement of the bed, the abutment 6 0 is carried by a pivotedarm 66, normally resting against a stop 67 to hold the abutment 6() inoperative position, as shown in Fig. 5, but free to be raised from thatposition, so that as the bed returns the abutment, engaging the upperside of the cam-plate 61, rides over the cam without moving the latch 55from its holding position.

It will be seen that the length of the web IOO IIC

fed between the feeding-rolls 41 and 42 and the length of the sheet cutfrom the web by the cutting-blades 44 45 depends on the distance betweenthe abutment 60 and the cam 62, carried by the bed, and it is evidentthat by changing the distance between said abutment and cam, by movingeither one or the other, the length of web fed between the rolls 4l and42 for each impression and the length of the printed sheet may bevaried. In the preferred construction shown the distance between theabutment and the cam, and consequently the length of web advanced foreach impression, is determined by the length ofthe form, one of saidmembers being arranged to move with the form-lock or movable member bywhich the form is secured on the bed.

In the machine shown the forward end of the form always occupies thesame position, the form being held against a stationary stop 70, and amovable form-lock 7l being provided to engage the rear end of the form,so as to accommodate forms of different lengths. As shown, the form-lockconsists of a body portion 72, which runs in a dovetailed groove 73 inthe frame at one side of the bed, and an arm 74, which carries aspring-seated bearing-plate 75. The bottom of the dovetailed groove 73is provided with a ratchet-rack 76, which is engaged by a spring-pressedpawl 77, carried by the form-lock and by which the form-lock is heldsecurely in place when it has been advanced to bring the spring-pressedbearing-plate 75 against the rear end of the form. The cam 62 is carriedby an arm eX- tending from a block 78, which is also held and guided inthe dovetailed groove 73 and which is connected with the form-lock 71,so as to be moved therewith. The cam 62 will thus be automatically adjusted with relation to the abutment 60, according to the length of theform on the bed.

In order to provide for varying the margin at the end of the printedsheet, the block 78, carrying the cam 62, is preferably adjustablyconnected with the form, as by the turnscrew 79.

The printed sheets are advanced from between the impression roll and theform through guides 8O and 8l to delivery-tapes 82 and 83. Any suitableinking mechanism may be employed.

It will be understood that the invention is not limited to the exactconstruction shown for the purpose of illustrating the invention and towhich the foregoing description has been mainly confined, but thatvarious changes and modifications thereof may be made Within the claims.
